Everything you need to know about those insane TSA lines plaguing airports

Usually, traffic outside of the airport is bad, with all the passengers coming and going. But now, it’s worse inside (as you probably know by now from traveling yourself or hearing complaints from other travelers), with recommendations to arrive at the airport three hours early, just for a domestic flight. The combo of more people flying and staff shortages (because of federal budget cuts) are the causes of the long TSA lines, according to CBS News.

Now, Delta has found their own solution to the problem: Innovation Lanes. Here’s everything you need to know about the in-sane TSA lanes and Delta’s fix (and why you may want to just fly Delta instead — or hope that more airlines catch on soon, and fast).

1. Five Bins At A Time

Instead of a bin at a time, five bins are done at a time, which means more people go through security at once (aka shorter lines — woo hoo!). And, you don’t have to wait to make sure your bin goes through. Then, the conveyor belt even gets the empty bins back to passengers who need them (isn’t it the worst when there are no bins?!), according to Popular Mechanics. So, in essence, more bins equals more productivity, which means shorter TSA lines — all without hiring more staff.

2. There’s A Separate Area For Bags That Need Further Checking

Another hold-up at TSA lines now is when someone’s bag needs to be checked by hand after it goes through the security machine. Of course it’s important, but it’s another way lines get out of control. Delta’s system, however, solves that issue by having such bags automatically re-routed to a different area, states Gizmodo.

3. The Innovation Lanes Are Only In Atlanta

But, before you get too excited, these Innovation Lanes are only in Atlanta at the moment… and there’s only two of them. But, like anything else, hopefully they’ll take off (no pun intended) at other airports, too, once people see how revolutionary and efficient they are.

4. They Cost (Like, $1 million!

Big ups to Delta for finding a solution to the TSA lines issue, though it cost them a lot — over $1 million. (Would hiring more people cost less? Time will tell.)

5. More TSA Employees Are On The Way (Hopefully)

Nearly 800 more security officers were supposed to be hired sometime in 2016, said CBS News, and they may now be working by mid-June. But some think that’s not nearly enough. The union that reps TSA officers think about 6,000 (!) employees need to be hired.

6. Innovation Lanes Or Not, Safety First

For non-Delta-in-Atlanta airlines, aside from hiring more screening officers, the U.S. Department of Homeland Security will have TSA employees work overtime. “We want to keep passengers moving, but we want to keep passengers safe,” Homeland Security Secretary Jeh Johnson said, according to CNN.
